A team of anthropologists studying Salorno, a stretch of scorched earth in northern Italy, say the site is a Late Bronze Age cremation platform where the remains of at least 172 individuals may have been burned. What’s more, the researchers believe the remains were simply left on the ground for the last 3,000 years.

The site is called Salorno—Dos de la Forca, and it dates from 1150 BCE to 950 BCE. Besides the cremains (cremated remains) researchers found charred animal bone fragments, pottery shards, and bronze burial goods. There was also a uniquely shaped boulder on the site (seen in the image above); it’s unknown whether it had any ceremonial purpose.
